A surgical instrument with articulated jaw structure includes a frame and two jaws. The jaws have proximal portions that are mounted to each other for movement in a substantially parallel relation between a fully open position wherein the jaws are separated for receiving tissue therebetween and an approximated position wherein the jaws are closer together. Preferably, the jaws are in the fully open position when the distal portion of at least of the jaws is located in an extended position and are in the approximated position when the distal portion of the extended jaw or jaws is located in a retracted position. The surgical instrument may further include a detachable knife assembly and knife actuating mechanism.

A stent for application within an aneurysm the stent comprising an elongated tubular member having a proximal end and a distal end. The stent has a proximal portion expandable from a first diameter to a second diameter. The distal end of the stent may be expandable to a third diameter, which third diameter is larger than the second diameter. The stent may be left disposed across the neck of the aneurysm.

Devices and methods for assessing the size, shape, and topography of vessel lumens and hollow portions of organs are described. The devices and methods are particularly adapted for determining the size, shape, topography, and compliance of the native heart valves to facilitate the later implantation of a prosthetic heart valve. The devices are typically catheter-based having an assessment mechanism fixed to a distal end of the catheter. The assessment mechanism generally includes an expandable member, such as a balloon. The assessment mechanism may also include an imaging member, a physical assessment member, an electronic mapping construction, an alignment mechanism, a valvuloplasty balloon, or any combinations thereof. The methods typically comprise deploying the balloon percutaneously to a target location, expanding the balloon, and determining one or more physical parameters associated with the target location.

A ground opening device includes a ground-penetrating element configured to penetrate a ground surface, a down drive element configured to apply a downward force to the ground-penetrating element, a reaction force sensor configured to sense a ground reaction force in response to the action of the ground-penetrating element, and a controller configured to adjust the downward force on the ground-penetrating element in response to the sensed ground reaction force.

An autostereoscopic display device has both a barrier arrangement and a lens arrangement. A plurality of views are provided to different lateral viewing directions. At least a portion of the field of view has autostereoscopic output, and the portion having autostereoscopic output has no repetition of individual 2D views and comprises at least three individual 2D views. This means there is no reversal of the stereo views (“pseudo stereo views”) at viewing cone boundaries as there are no viewing cone boundaries.

An earplug (7) for a hearing aid (1), in particular for a BTE-type hearing aid, has a front end (8) and a rear end (9). The front end (8) is adapted to be inserted into an ear canal of a wearer. The earplug (7) comprises a main body part (10) comprising a longitudinal bore (11) extending along a centrally arranged axis (A-A) of the earplug (7), and at least one sound output passage (17) in communication with said longitudinal bore (11) and leading to a sound output opening (18). The earplug also has a collar (19), which is adapted to engage the wall of an ear canal and surrounds the main body part (10). The output opening (18) has at least one edge part (18a) located in a retracted manner with respect to said front end (8).

In a drive apparatus having an integrated structure where a rotating electric machine and an inverter and a voltage converter for driving the rotating electric machine are integrally stored in a case, lubricant oil carried up by the rotation of the motor-generator flows into a storage chamber for a reactor from an opening. The lubricant oil flown from the opening is stored inside the storage chamber with the use of a dividing wall provided between a portion where the motor-generator is stored and the storage chamber, whereby at least part of reactor is immersed in the lubricant oil. Thus, the performance of cooling the reactor is ensured.

A biopsy needle scrapes tissue of cellular thickness from a lesion during repeated proximal-to-distal thrusts of the needle along its longitudinal axis of symmetry. A first sharp edge, formed by a beveled distal end of the needle, scrapes tissue during proximal-to-distal travel of the needle. A second sharp edge is provided by a transversely disposed slot formed in the needle near the first sharp edge. The second sharp edge also scrapes tissue during proximal-to-distal travel of the needle. The second sharp edge may be coincident with an exterior surface of the needle elevated with respect to the exterior surface, or recessed with respect to the exterior surface. Another embodiment includes a hinge for enabling pivotal movement of the second sharp edge.

The invention provides a shear type expansion anchor rod which comprises a fixing part, a pushing part and a tightening part, wherein the fixing part is provided with an expansion part. The shear type expansion anchor rod is characterized in that the pushing part is matched with the fixing part, the pushing part and the fixing part can move along the coaxial direction of the axis of the fixing part, the expansion part is hinged with the top end portion of the fixing part, the lower end portion of the expansion part is provided with an inclined surface facing the pushing part, the top end portion of the pushing part can contact with the inclined surface of the lower end portion of the expansion part and pushes the expansion part along the inclined surface, the expansion part is stretched in a shear mode towards the outer side of the pushing part, and the tightening part is arranged at the lower end of the pushing part and can move in the coaxial direction of the axis of the pushing part. The shear type expansion anchor rod is simple and ingenious in structure, the expansion part is stretched in the shear mode, the stretched range is large, anchoring force is strong, and the shear type expansion anchor rod not only is used for surrounding rock support and protection, but also is widely suitable for anchoring or fixation of mines, tunnels, protection slops, foundation trenches, buildings and other engineering. Extension application comprises underpinnings for constructing the buildings, stand columns for highway sides, and the like, and safety, reliability and universal values of the shear type expansion anchor rod are achieved really.

An opening and closing mechanism for a cover is openable and closable with respect to a body. The mechanism includes a link structure supported at the body rotatably within a range of a first predetermined angle from a closed state of the cover, and supporting the cover rotatably within a range of a second predetermined angle. The link structure is rotated integrally with the cover when being rotated within the range of the first predetermined range. The cover is solely rotated within the range of the second predetermined angle when the link structure has been rotated by the first predetermined angle from the closed state of the cover.

An equipment rack includes a frame, a first pair of mounting rails and a second pair of mounting rails. Each pair of mounting rails includes a front mounting rail and a rear mounting rail and the front and rear mounting rails each include a first planar surface defining in part a first equipment-mounting interface when the front and rear mounting rails are coupled to the frame through a second planar surface of each of the front and rear mounting rails in a first configuration. The front and rear mounting rails each further include a third planar surface and a fourth planar surface defining in part a second equipment-mounting interface when the front and the rear mounting rails are coupled to the frame through the first planar surface in a second configuration. The first and second equipment-mounting interfaces can be defined by an equipment rack standard.
